Welcome to the AirstreamForums! Congratulations on your "new" 1964
, I hope you get as much enjoyment from yours as we have ours!
, clear coat was an "option", some had it some didn't. Ours did. The easiest way to figure out if yours does is:
Test #1 = Is it evenly oxidized or splotchy looking?
Answer #1 = If evenly oxidized, either you have no clearcoat or your clearcoat is intact. If splotchy, milky or peeling...you have clearcoat, which needs to be removed first.
Test #2 = Wash a small area with water. Put a dab of toothpaste on your finger and gently rub it on the clean area. If it turns "black" you don't have clearcoat or your clearcoat is failed. If it's not splotchy from Test #1, you don't have clearcoat. If it doesn't turn black, you have intact clearcoat.
Once you've determined if you have clearcoat or not, if you want to polish you will need to remove the clearcoat first if you have it, even if it is failed. As far as stripping and polishing goes, there are as many opinions on how to do it as there are polished trailers. You may want to do a search here on the forums (button, top right) to read about a few of them.
Polishing a trailer is a big commitment of time, money or both. Be sure you really want to take it on before you start...we've done it
and don't regret it
, but it is a labor of love.
Good luck in whatever you decide to do.
